Packaging Lettuce Heads

A FANUC R-2000iB removes trays of lettuce and pours the contents onto a conveyor for packaging. This system is capable of packaging 550,000 lettuce heads per day. A vision system then measures the shape and form of the lettuce and determines where to cut the root. A FANUC LR Mate 200iB then helps to perform a second check on the size of the lettuce. Lettuce heads that pass this final test are packaged into plastic containers while items that fail are rejected and discarded. The robots have decreased rejected items by 15%.
